摘　　要：在实时仿真发电机一电网的环境下测试励磁调节器的性能是十分有意义的。文中提出了一种基于数字信号处理器(DSP)的发电机励磁仿真测试系统,详细地介绍了励磁系统各个环节的实用数学模型、实时数据的采样和数字滤波、快速傅里叶变换(FFT)等算法。现场试验证明,该系统能够很好地仿真测试励磁系统的各个环节,测试自动化减轻了测试工程师的负担。The testing of the performance of an excitation system in real-time simulation of a synchronous generator is of significance. A DSP-based instrument for the simulation and testing of excitation systems is proposed. The mathematic models for every part of excitation systems are described. The sampling of real-time data, and the algorithm of digital filter and fast Fourier transformation (FFT) are presented. Field experiments demonstrate that the excitation systems can be well simulated and tested with the proposed instrument.
